摘　　要：利用1996～2007年中国17个高技术产业的面板数据，选用Malmquist-Tobit两步法实证分析了不同R＆D投入主体对高技术产业的创新绩效及其分解变动的影响。本文的分析结果表明，1996—2007年间高技术产业整体的创新绩效提升原因在于技术进步水平的提高，技术效率对创新绩效的负向作用主要源于规模效率低效，即整体产业的规模结构不合理是制约中国高技术产业创新绩效提升的主要原因。Using the panel data of 17 individual high - tech industries from 1996 to 2007 and the methods of Malmquist - Tobit,this paper presents an empirical study of the influence of difference source of R＆D inputs on innovation effieieney in Chinese high- teeh industry and its subdivisions. The results indicate that technology progress promotes the innovation efficiency level while technology efficiency are partly offset this trend cause a slower innovation efficiency improve in the whole. The authors find that the main source of the negative impact of the technology efficiency on innovation efficiency is the scale inefficiency, that is, the main constraining factor in improving the innovation efficiency of the high - tech industry in China is the unreasonable scale structure of the whole industries.

关 键 词：创新绩效 Malmquist—Tobit两步法 技术进步 规模效率
